dihedral
Where planes meet
A dihedral is the angle formed where two planes meet, like the pages of an open book.
In aircraft design, dihedral describes the upward angle of wings from the fuselage—a configuration that improves stability: The plane's pronounced dihedral made it forgiving for new pilots.
Mathematicians and chemists use the term for angles between intersecting planes in molecules and crystals.
